This is one of a number of drawings made of the temple complex at the same time as that of the Temple of Diana in Adam vol.57/14. There are other views of the Temple of Diana in Adam vol.57/33 and 57/38, the latter by Charles-Louis Clérisseau, which also shows the Temple of Venus. Both temples were part of the same large complex of baths dating from the 1st to 3rd centuries AD. A plan and an account of these buildings is given in Paoli, Avanzi Delle Antichita Esistenti a Pozzuoli Cuma e Baja, Naples, 1768, f.32, and a view of the vaults that Robert Adam depicted appears as pl.LV, 'che chiamansi Truglio', that is, 'cave'. Two vaults are shown in the foreground here, while in Adam vol.57/23 three vaults are shown, with the Temple of Venus in the distance. All three drawings show Adam and Clérisseau assessing the picturesque values of each scene.
